SPECIFICATION forming part of Letters Patent N o. 747,138, dated December 15, 1903- Application filed .Tune 19I 1902. Serial No. 112,372. (No specimens.)

.To all whom it may concern.-

Beit known that I, JOSEPH OHOULET, a citizen of the French Republic, residing at 83Rue de Constantine, Algiers, Algeria, have invented certain new and useful Improvements in Disinfectants and Processes of Making the Same,of which the followingisaspecification.

This invention relates to a new application of acetylene, which application is based on the observation that dissolved and atomized or combined with other means in ordinary use acetylene is eminently suitable for disinfection purposes, and more especially for the destruction of insects, larvae, &c., and any kind of injurious germs. It permits by more economical means of obtaining more durable and more complete results than those hitherto obtained. Thus for the treatment of vines solutions or pulps of sulfate of copper in water are generally used, the said solutions being atomized by gas-pressure, the gas employed being either atmospheric air or carbon dioxid. If calcic carbid is thrown into a solution of this kind, the action of theV water of the solution will produce an evolution of nascent acetylene gas which will mix or combine with the solution now become a pulp-that is, a mixture of copper-sulfate solution and lime-and will in consequence of the pressure with which it is generated cause the jet required for its atomization. In the case where carbon dioxid is used this gas remains perfectly neutral and does not transform the solution into a pulp.

In carrying my invention into practice I use an apparatus of which I will now describe a few constructional forms with reference to the accompanying drawings, of which- Figure l is a vertical section of an atomizer of usual form, wherein calcic carbid contained in a boxwith a jointed bottom is thrown into water placed on the bottom of the atomizer. Fig. 2 is a top view of the same. Fig. 3 is a separate view of the basket containing calcic carbid. Fig. 4 shows an arrangement intended to prevent the escape of solid particles. Fig. 5 lis a vertical section of an apparatus working by inverting. Fig. 6 is a top view of the same.

The atomizer consists of a cylinder a, preferably of sheet-iron, the ends b of which are dished outward. a central opening closed by a cap c, kept hermetically closed by wedges d. The cap is provided with a box or basket e, having a jointed bottom f, kept closed by a lever y, pivoted midway of its length to a rod h, attached to the body of the box or basket. To the lower end b and inside the cylinder are attached rods z', terminating at -their lower ends in tappetsj. These rods are arranged at two diametrically opposite points relatively to the axis of the box e and near enough 4to the box to be met by the levers g and stop them on their passage. At the lower part of the cylinder is a iexible tube 7c, at' the end of which is attached the nozzle for atomizing the jet.

Fig. 4 shows a device for preventing the escape of particles, which consists of a wiregauze basket m, kept in a state of rigidity by a spring n or by the wire-gauze being sufficiently rigid.

A safety-valve r is provided, which is attached to the part in which the gas evolved by the working of the apparatus accumulates. This valve is so set as to let the gas escape when it is produced in excess.

The apparatus may be provided with an Vappliance such as a curved sheet-iron plate o, suitably shaped to enable the apparatus to be carried onl the back of a man.

The mode of operation is as follows: The fluid is introduced into the cylinder at the level of the plug q and then carbid of calcium is placed in the box or basket e. The box or basket is then closed by placing vertically'the lever g, as shown in Fig. 1. The box or basket is then put in place and the apparatus closed, and by a quarter of a turn the closing becomes hermetic. During this movement the lever is stopped by lone or other of the rods i and in turning on its center frees the bottom fof the carbid box or basket. The carbid falls in the water and immediately produces a liberation of nascent acetylene gas, which is mixed and combined with the iuid and the pressure of which has for effect to drive through the pipe 7c the pulp so produced.

As illustrated in Figs. 5 and 6, the box or basket may be made of a metallic gauze p,

One end is provided with IOO independent of the means of closing the cylinder, and be fixed in place by the closure of the cover. To operate this apparatus, fluid is introduced as before, the box or basket is put in place, then reversed, after having been closed by turning the cork closure. Water enters the box or basket, chemical action results, and a pulp is formed.

The fluid may be a copper solution, such as a copper-sulfate solution, or any other suitable solution, or Water alone, the action ofthe acetylene alone being suflicient in certain cases.

Having now particularly described and ascertained the nature of my invention and in what manner it may be performed, I declare 1. The herein-described process for producing a disinfectant, which consists in first adding calcic carbid to a suitable sulfate solution, then causing the resultant nascent acetylene gas and the pulp produced from said solution to mix, and finally atomizing said mixture.

2. The herein-described process for produc-ing a disinfectant which consists in adding calcic carbid to a suitable sulfate-ofcopper solution, then causing the resultant nascent acetylene gas and the pulp produced from said solution to mix, and finally atomizing said mixture.

3. The herein described disinfectant, which consists of the product formed by mixing calcic carbid and a suitable sulfateof-copper solution, said disinfectant being characterized by the presence of acetylene.

In testimony whereof I have hereunto set my hand-in presence of two subscribing Witnesses.

JOSEPH CHOULET.
